Will this be fixed in other Unity versions such as 6000.0, and 6000.3?

"Under consideration for 2022.3.X, 6000.0.X, 6000.3.X, 6000.4.X"
Really?
This is a very serious problem that affects thousands of games, where projects clearly cannot be switched to a version that does not officially exist yet.
Then what does "LTS" mean in those version names?

This is the same issue I faced in my project, and I reproduced it in this Unity 2022.3.62f3 example:

It is unbelievable that this serious issue is still not fixed, as it renders games unenjoyable on macOS.

I'm not 100% sure but I think the stutter happens even with Vsync OFF on Mac. But because there is a lot of screen tearing it's harder to see the stutter. Turning Vsync ON helps the stutter to be more visible.

This is a critical issue! It's not possible to release anything on MacOS as long as this remains unresolved.
Please advise any workarounds that can be applied locally.
